| 摘 要： | 使用空间无关的公平性衡量指数评价公交服务时,会忽视公交服务需求与供给的空间分布特征。为解决此问题,论文提出基于空间公平理论的公交服务评价框架,即通过构建综合基尼系数与莫兰指数的空间公平评价方法,实现整体尺度公交服务评价;通过对分析单元上相对需求与相对供给变量的匹配关系、空间差距进行分析,实现局部尺度公交服务评价,对整体尺度结果进行补充。深圳市的案例研究表明：① 基于平等主义的整体尺度空间公平指数显示,空间公平性最好与最差的行政区均位于中心城区,分别为罗湖区与南山区;② 局部尺度分析结果进一步印证,单一使用基尼系数评价公交服务存在局限性,相同或接近的基尼系数可以对应完全不同的公交服务不公平状态与供需匹配情况。 |

| Abstract: | Using aspatial equality measurement index to evaluate public transport services may overlook the spatial agglomeration relationship of the demand and supply of public transport services. Therefore, a public transport service evaluation framework based on spatial equality theory was proposed—at the global scale, an evaluation method that integrates the Gini coefficient and Moran's I indicator was developed, and at the local scale, a spatial gap analysis was employed to explore the coupling relationship between demand and supply at each analysis unit. The case study of Shenzhen City revealed that: 1) The egalitarian-based spatial equality index shows that the administrative districts with the best and worst spatial equality status are both located in the downtown area of the city, which are Luohu and Nanshan districts. 2) The local scale evaluation visually displays the demand and supply gaps and matching status at each analysis unit. The results indicated that there exist limitations in the use of the Gini coefficient alone when conducting public transport service evaluation—the same or similar Gini coefficients can correspond to completely different service supply and demand matching status. |
